Captain Swan 'shippers, get ready to start your engines. In this Sunday's (May 11) Season 3 finale of
"Once Upon a Time," Emma and Hook accidentally get sent back in time together to Fairy Tale Land of the past, and you know what that means: Plenty of Emma/Hook banter to sink your teeth into as they fight to make their way back to the present.

Zap2it has an exclusive clip from the finale, featuring one of the cutest Emma/Hook scenes yet. Emma may be hating her old-fashioned dress, but Hook sure has some nice things to say about it. And is that a smile we see on Emma's face? Yes, yes it is. Squee!

Plus, are Emma and Hook ... royals? Watch the exclusive clip below to find out their hilarious royal titles. The two-hour "Once Upon a Time" Season 3 finale airs Sunday (May 11) at 8 p.m. ET/PT on ABC.
